Gabions used to create an outlet into the river from waste water

I used the gabions to create an outlet into the river from my waste water and surface water system in the house. The previous one had collapsed years ago and I was given the design, which you are welcome to use, by the Wyre (Lancashire) river authority as their best design for this sort of work. It is basically gabions complete with a “mattress” below surface and stacked and wired together with a concrete section in the middle to take the outlet pipe.
